To limit global warming in 2100 to below 1.5°C above pre-industrial levels, many scientists assume that the large-scale use of negative emissions in the latter half of the 21st century will be needed. Negative emissions “suck” CO2 out of the atmosphere, allowing a more gradual reduction of emissions in the near-term

May 21, 2018 — Integrated assessment models (IAMs) that generate energy and emission pathways to limit warming to 1.5°C have generally relied on large amounts of bioenergy with carbon capture and storage (BECCS) to provide the required negative Continue reading Analysis: How ‘natural climate solutions’ can reduce the need for BECCS

UK to miss legal climate targets without urgent action, official advisers warn

Vague ambitions, such as banning new petrol cars by 2040, must be turned into solid plans, says the Committee on Climate Change

January 17, 2018 — The UK will miss its legally binding carbon targets without urgent government action, official advisers have warned. Continue reading UK to miss legal climate targets without urgent action, official advisers warn

Ancient peatlands that store huge amounts of carbon are under threat from logging

November 12, 2017 — Stumbling on submerged roots, attacked by bees and wading waist-deep through leech-infested water, the three researchers and their Pygmy guides progress at just 100 metres an hour through the largest and least-explored tropical bog in the world. Continue reading Congo basin’s peaty swamps are new front in climate change battle

Green co-leader Caroline Lucas says she hopes to build a cross-party coalition to stop bottle wastage, while other correspondents offer their thoughts on protecting the environment

June 30, 2017 — The Guardian’s coverage of the global plastic bottle crisis (Surge in plastic bottle use sparks global alert, 29 June) has been powerful and compelling. Like so many of the environmental Continue reading Tackling the plastic bottle crisis and our wider disregard for nature

Can more trees, carbon capture or biochar solve our CO2 problem

As CO2 levels rise, controversial techniques including carbon capture and storage, enhanced weathering and reforestation may be solutions

May 5, 2017 — In the 2015 Paris climate agreement, 195 nations committed to limit global warming to two degrees above pre-industrial levels. But some, like Eelco Rohling, professor of ocean Continue reading Can more trees, carbon capture or biochar solve our CO2 problem

Cut fossil fuel use ‘dramatically’ to meet climate goals, says Shell-backed report

The use of fossil fuel, particularly coal and oil, must decline “sharply” if the world is to meet the goals of the Paris accord, according to a new report backed by energy giants Shell and BHP Billiton

April 25, 2017 — Global coal use must be cut by 70% within 25 years, oil use must fall 30% and gas can increase by only 2% out to 2040. The growing global population will instead get its energy from Continue reading Cut fossil fuel use ‘dramatically’ to meet climate goals, says Shell-backed report

This is a guest post by Dr Jo House, reader in environmental science and policy at the University of Bristol’s Cabot Institute, and Dr Giacomo Grassi, scientific officer at the Joint Research Centre of the European Commission.

February 27, 2017 — The Paris Agreement on climate change set new targets for the world. Notably, it called for warming to be limited to “well below” 2°C and for carbon neutrality (“net zero”) by the second half of this century. Continue reading Forests to provide a quarter of Paris Agreement’s pledged mitigation

Victoria’s plans for hydrogen exports to Japan are ‘way of making brown coal look green’

Proposed plant would would be run by Kawasaki Heavy Industries and produce liquid hydrogen for use in vehicles

January 12, 2017 — Victorian government plans to work with a Japanese company to produce hydrogen from brown coal in the Latrobe Valley are “a way of making brown coal look green”, according to one expert.  Continue reading Victoria’s plans for hydrogen exports to Japan are ‘way of making brown coal look green’

A guest article by Sam Hampton, a doctoral researcher at the Environmental Change Institute. Hampton was one of the rapporteurs at the 1.5 Degrees conference which took place in Oxford last week. Carbon Brief also reported from the conference

September 29, 2016 — Last week, the University of Oxford’s Environmental Change Institute (ECI) held a conference aimed at responding to the ambitious target set by the Paris Agreement to “pursue efforts” to limit global temperature rise to 1.5°C.  Continue reading What technologies are available for meeting the 1.5C goal

UK must move now on carbon capture to save consumers billions

Kickstarting the carbon capture and storage industry with a state-backed company will deliver the clean electricity needed to meet climate targets more cheaply than Hinkley Point C, says government advisory group

September 12, 2016 — The UK must immediately kickstart an industry to capture and bury carbon emissions in order to save consumers billions a year from the cost of meeting climate change Continue reading UK must move now on carbon capture to save consumers billions
