Britain Adopts 2050 Net Zero Emissions Target

You may have seen this headline banded around in the news over the last few weeks, and for good reason – it’s a significant breakthrough towards a low carbon future, with Britain leading the way by adopting this hard stance.

So, what exactly does net zero emissions mean?

Essentially, net zero emissions mean that every home, business, transport type, and industry in the UK must completely cut, or offset, their greenhouse gas emissions by 2050.

This is an even more ambitious target than the goal of reducing emissions by 80% but has been advised by the Committee on Climate Change as being a necessity to avoid the 1.5C rise in temperature by 2100.

The UK is the first of the G7 Group to make this commitment

We’ve already seen commitments to achieve net zero emissions, including Finland who aim to achieve this by 2035 and Norway by 2030. Closer to home, Scotland has already committed to achieving this goal by 2045.

However, the UK is the first of the G7 group of industrialised nations to implement a net zero emissions legislation.

This is a large statement and is one that’s been designed to encourage other members of G7 to follow suit. The report claimed that if other countries also committed to an aggressive reduction of greenhouse gas emissions then there is a 50-50 chance that the world will stay below the 1.5C threshold for dangerous climate action.

In a recent session, PM May urged the G20 countries to act on climate change and set targets for net zero greenhouse gas emissions. During this session, 19 of the 20 leaders committed to the “irreversibility” of the 2015 Paris agreement and the full implementation of its targets. The only member who did not sign was US President Donald Trump.

This move adds extra weight as Britain is the birthplace of coal fired power generation, one of the biggest contributors to carbon emissions. By adding historical responsibility to carbon emissions, Britain is the world’s top contributor closely followed by USA, Canada, Russia and Germany.

How the UK will achieve net zero emissions

The strategy for this goal has yet to be laid out, but there have been a number of recent moves from the government which can give us some idea.

For example, the UK are investing £26million into nine carbon capture projects to help accelerate the roll out of this technology. One of these nine projects is Tata Chemicals Europe plant in Cheshire, the largest carbon capture, utilisation and stores project to date – this one plant alone would look at capturing and utilising 40,000 tonnes of carbon dioxide each year.

Additionally, the government has pledged to plant 3 billion trees by 2050, with the majority of them being planted with the first 15 years of this project. This is a highly ambitious goal and equates as 270,000 trees planted every single day.

To make net zero emissions a reality, the UK will need to fundamentally rethink many ways of working – from businesses, to manufacturing to the home. There will likely be a big push for more renewable energy sources, with projects like Swansea Tidal Lagoon offering a consistent, large scale source of power.

In 2018 alone, more than 13 gigawatts of clean energy contracts were signed. In the last two years we’ve seen a large uptake in the number of renewable energy projects being adopted – specifically wind generation, with a huge push in 2017-18 for more offshore wind, taking the UK to nearly 20 terawatt hours of installed capacity.

The impact on businesses and people

Currently, the legislation allows a loophole for international carbon credits which can allow corporations to effectively buy net zero emissions. Many, including Greenpeace and the chair of the Committee of Climate Change, have warned against such credits as it can shift the burden to developing nations.

While some businesses may take this loophole approach and simply pay to offset their carbon consumption, the aim is that most businesses and individuals will be taking drastic steps to lower emissions either by reducing their consumption or utilising clean energy sources.

In extreme cases, we may see restrictions or higher tax on high-carbon meats, such as beef, or even a clamp down on flying. However, this is unlikely to happen due to the opposition these political decisions would face.

It’s more likely that we’ll see a much greater investment in the “clean revolution” to allow for a painless transition into net zero emissions. This has already started to take place with the number of manufacturers who have started to produce electric cars, as well as the news last month about the infrastructure investments.

For this infrastructure and innovation to happen, it requires heavy investment and currently the government hasn’t stated who will be covering this cost – bill payers, tax payers or fossil fuel firms.

Net Zero Emissions on an international level

While these targets have been set by the UK, in order for them to be truly hit they cannot be done entirely at home. There’s a huge amount of international collaboration that is needed to ensure that net zero is achieved.

To align with this goal, fuel imports, produce imports and overseas manufacturing all need to be net zero carbon. This relies on putting pressure on international trade deals to meet these standards, something which will need to be heavily driven by businesses across the UK.

What about the cost?

Chancellor Phillip Hammond warned that this new target would likely cost the UK £1trillion by 2050. This is a figure that Bjorn Lomborg, of Skeptical Environmentalist, likely believes is underestimated against the true cost. However, this doesn’t take into account the benefits that cleaner air will have on the health system or the number of clean energy jobs that will be created.

The acting energy minister, Chris Skidmore, claimed that the costs for this would be between 1 and 2% of the UK’s GDP – an amount which was already factored in for the pre-existing 80% reduction target. This would mean that money would not have to come from elsewhere in order to meet these targets.

The cost of doing nothing

While many may hesitate at the cost of tackling climate change, the cost of doing nothing is even more extreme. Just from a health perspective, the WHO estimate that exposure to air pollution causes 7 million deaths worldwide and costs US$5.11trillion in welfare losses globally each year.

There are lots of estimates for the social cost of carbon (SCC) which looks at the costs to society for the negative consequences of climate change. This factors in things from increased health requirements due to air pollution through to land lost from rising sea levels and much more.

Predicting SCC isn’t an exact science and as such there are many different estimates – in the Journal of Cleaner Production, they argue that the current SCC is US$112.86 per tonne of carbon.

Based on 2018 figures, which were 2.5% lower than 2017, the UK’s carbon emissions would have an SCC of US$41.1trillion or £32.6trillion each year. Over the next 30 years, that would be more than 960 times the amount that Chancellor Phillip Hammond believes the UK would pay in order to achieve net zero emissions.

What can my business do to help achieve Net Zero emissions?

Taking action is simple and it doesn’t necessarily mean that you need to change the way your business operates.

One of the simplest things you can do is move to a renewable tariff – at amber we’re a green energy consultant and can help you move to a tariff that’s better for the environment without costing you the world.

We’d also recommend looking at your current levels of efficiency and start implementing quick wins and scoping long term projects to improve your baseline energy consumption. Not only will this help to reduce your business overheads, but you’ll lower your carbon footprint at the same time.

The role of carbon capture, utilisation and storage (CCUS)

Carbon capture, utilisation and storage (CCUS) is set to play a pivotal role in the UK’s journey to net zero. The technology captures carbon dioxide emissions from industrial processes and power generation, preventing them from entering the atmosphere. Once captured, the CO2 can be permanently stored deep underground in geological formations or utilised in products such as building materials, chemicals, and fuels.

The UK has a strategic advantage in deploying CCUS due to its extensive North Sea oil and gas infrastructure, which can be repurposed for CO2 transport and storage. The government’s £26 million investment in nine carbon capture projects is a clear signal of intent, but scaling up will require significant private investment and a supportive policy framework. By 2030, the UK aims to capture 10 million tonnes of CO2 per year, equivalent to the emissions of around 4 million cars.

Decarbonising heat and transport

Two of the most challenging sectors to decarbonise are heat and transport. Currently, around 85% of UK homes use natural gas for heating, and transport remains the largest emitting sector. The transition to low-carbon heating will likely involve a mix of heat pumps, hydrogen boilers, and district heating networks. The government has set a target of 600,000 heat pump installations per year by 2028, up from around 60,000 in 2023.

For transport, the ban on new petrol and diesel cars from 2030 (brought forward from 2040) will accelerate the shift to electric vehicles (EVs). However, this requires a massive expansion of charging infrastructure and a greener electricity grid to ensure EVs are truly zero-emission. The government has committed £1.3 billion to roll out EV chargepoints in homes, streets, and motorways across England.

Financing the transition

One of the biggest questions surrounding the net zero target is who pays for it. The Climate Change Committee estimates that the total investment needed across the UK economy is around £50 billion per year by 2030, falling to £40 billion per year by 2050. While this is a significant sum, it represents just 1-2% of GDP and is expected to deliver long-term savings through reduced energy bills and health benefits from cleaner air.

The costs will be shared between government, businesses, and consumers. The government has already announced a £12 billion Ten Point Plan for a Green Industrial Revolution, which includes funding for offshore wind, hydrogen, nuclear, and EV infrastructure. However, there are concerns that the burden could fall disproportionately on lower-income households, who spend a higher proportion of their income on energy. Policies such as the Warm Home Discount and Energy Company Obligation (ECO) will need to be expanded to ensure a just transition.

What businesses can do to prepare

Businesses of all sizes will need to adapt to the net zero economy. The first step is to measure and understand your carbon footprint. This includes direct emissions from your operations (Scope 1), indirect emissions from purchased electricity (Scope 2), and emissions from your supply chain and product use (Scope 3). Once you have a baseline, you can set science-based targets to reduce emissions in line with the Paris Agreement.

Key actions for businesses include:

Switching to renewable energy tariffs or installing on-site generation like solar panels.
Improving energy efficiency through insulation, LED lighting, and smart building controls.
Electrifying your vehicle fleet and encouraging sustainable commuting.
Engaging suppliers to reduce upstream emissions and choosing low-carbon materials.
Investing in carbon removal projects to offset residual emissions, but only as a last resort.

Early movers will gain a competitive advantage as customers, investors, and regulators increasingly demand climate action. For more practical advice, read our article on 5 opportunities helping UK businesses get to net zero.

The path ahead: milestones and monitoring

The UK’s net zero target is legally binding, but achieving it will require sustained political will and public support. The Climate Change Committee will publish annual progress reports to Parliament, highlighting where the government is on track and where it is falling short. Key milestones include:

2025: All new homes to be zero-carbon ready; 40GW of offshore wind capacity.
2030: Ban on new petrol and diesel cars; 10 million tonnes of CO2 captured per year; 5GW of low-carbon hydrogen production.
2035: All electricity to be generated from low-carbon sources; phase-out of new gas boilers.
2050: Net zero emissions across the entire economy.

While the challenge is immense, the UK has already reduced emissions by over 40% since 1990 while growing the economy by 75%. The net zero transition presents an opportunity to build a cleaner, healthier, and more prosperous future for all.
