Reducing our Carbon Emissions

Reducing greenhouse gas emissions is essential to prevent further increases in average global temperatures and the extreme impacts of climate change.

Carbon dioxide (CO2) is the most significant greenhouse gas and the UK has a target to reduce CO2 emissions by 34% by 2020 (from 1990 levels). There is a legally binding agreement to reduce carbon emissions to zero by 2050.

Carbon (CO2) emissions are calculated for local authority areas by BEIS.These have been reported since 2005, the baseline year and are measured in thousands of tonnes (kT) of CO2. Local action is critical to the achievement of the Government’s objectives. The Island’s total carbon emissions in 2005 were 776,000 tonnes (tCO2) or 5.7 tCO2 per person. These had fallen to 496,000 tonnes (tCO2) or 3.5 tCO2 per person by 2017 (this is the latest available data).

In 2005, Island carbon emissions were 776 kT. Industry and commerce accounted for 317.5.4 kT; the domestic sector for 344.8 kT and transport for 135.9 kT. Using a mid-year population estimate of 137,200 this equates to 5.7 tonnes per capita (per person).


Carbon Reduction: Progress to Date


The Island's per capita carbon emissions have fallen from 5.7 tonnes CO2 per person in 2005, to 3.5 tonnes CO2 per person in 2017. The annual reductions are shown in the table below.:

Year   Tonnes CO2 per person
 2005  5.7
 2006  5.5
 2007  5.3
 2008  5.2
 2009  4.6
 2010  5.2
 2011  4.6
 2012  4.9
 2013  4.6
 2014  4.1
 2015  4.0
 2016  3.8
 2017  3.5


Carbon emissions have fallen from 778,000 tCO2 in 2005, to 496,000 tCO2 in 2017, a reduction of 282,000 tonnes of CO2 or 36%, an average reduction of 3% per year.The biggest falls have been in the domestic sector (-140 tCO2) and the industrial and commercial sector (-119 tCO2) with a much smaller decrease than the transport sector (-14 tCO2).
