Climate change is speeding up, and we can’t ignore it any longer. Baroness Sheehan, who heads the Environment and Climate Change Committee, argues that 2026 must see real, evidence-based actions to protect our environment, cut emissions, and restore the UK’s climate leadership.
The idea that achieving net-zero emissions is optional is a dangerous myth. Climate change is real and affects us daily. While we have some measures in place, they are not enough for the scale of the problem we are facing.
Recent data shows global emissions are still rising. In 2025, atmospheric CO2 levels hit around 426 ppm, which is about 52% above pre-industrial levels. Researchers emphasize that we must stop using fossil fuels and protect vital carbon sinks like forests and wetlands. Studies indicate that we are nearing tipping points in several natural systems, making urgent action crucial.
To combat this, we need strong government leadership. In 2024, the UK Infrastructure Bank was repurposed to attract private investment in clean energy and regional development. The Great British Energy Act from 2025 set up a public energy model to drive progress toward net-zero. However, 2026 needs to go further. We are still waiting for a Land Use Framework to allocate land for various uses and promote both mitigation and adaptation. Additionally, the outcomes of the Cunliffe Water Review are eagerly anticipated, especially since nature-based solutions could improve water quality and drought readiness.
The potential of community energy remains untapped, and leveraging it could lower costs and foster community support. In 2026, addressing the high price of electricity is also essential.
As we move forward, protecting carbon sinks must be a priority even as we expand renewable energy. The UK’s past failure to support the Tropical Forest Forever Facility was a mistake. In 2026, reversing this and enforcing the Environment Act of 2021 to ensure due diligence for forest-risk products will be vital. We also need to clarify and protect natural carbon stores within our Farming Roadmap and identify new tree-planting sites.
“Parliamentarians must continue to press for momentum.”
Another crucial area needing immediate action is short-lived climate pollutants, particularly methane. A report by the committee identified methane reduction as a simple yet effective way to cool the planet. However, the government’s 2025 Methane Action Plan was criticized for its lack of specific goals. The upcoming year must include clear targets and timelines for reduction.
Parliamentarians must keep pushing for progress, advocating for green growth, and implementing strong protections for carbon sinks. Effective leadership calls for clear, evidence-based plans that involve the public and stakeholders. The government should outline a 2026 agenda linking land use, farming, energy, and industry to net-zero goals while also tackling energy costs and community involvement. By doing so, the government can showcase real climate leadership and promote economic growth.
