Tightening the Net: Report by Oxfam

In News

Oxfam has recently published a report titled “Tightening the Net” just a few months ahead of the UN climate talks in Glasgow.

Key Findings of Report

  • ‘Net zero’ carbon targets that many countries have announced maybe a “dangerous distraction” from the priority of cutting carbon emissions.
  • “Land-hungry ‘net zero’ schemes could lead to
    • an 80 per cent rise in global food prices. 
    • more hunger.
    • allowing rich nations and corporations to continue “dirty business-as-usual.

What is the meaning of Net Zero?

  • A state in which a country’s emissions are compensated by absorption and removal of greenhouse gases (GHGs) from the atmosphere is called Net Zero State.
  • Net-zero is also referred to as carbon-neutrality.
  • It does not mean that a country would bring down its emissions to zero. 

How is it Different from Gross-Zero?

Gross Zero

Net Zero

A state where there are no emissions at all.

Emissions are compensated by absorption or removal of equivalent GHGs

Very hard to achieve.

Promised by many countries.

More Beneficial for the environment and ultimate goal.

Less beneficial and may distract the world as per IPCC report.

How Net Zero is Achieved?

  • By creating carbon sinks by growing forests. 
    • Until recently, the Amazon rainforests in South America, which are the largest tropical forests in the world, were carbon sinks.
      • But eastern parts of these forests have started emitting CO2 instead of absorbing carbon emissions as a result of significant deforestation.
    • A country may also have negative emissions if the absorption and removal exceed the actual emissions. 
      • Bhutan has negative emissions because it absorbs more than it emits.

Which Countries have Recently Announced Net-Zero Targets?

  • The New Zealand government passed the Zero Carbon Act in 2019.
    • It committed to zero carbon emissions by 2050 or sooner to meet its Paris climate accord commitments. 
  • In 2019, the UK passed legislation to reduce its net emissions of GHGs by 100 per cent relative to 1990 levels by the year 2050.
  • Recently, the USA also announced its plans to cut its greenhouse gas emissions by at least 50 per cent below 2005 levels by 2030. 
    • John Kerry launched a bipartisan organisation called World War Zero in 2019. 
      • He is the USA’s climate envoy and considered one of the chief architects of the Paris Climate agreement
    • World War Zero aims to bring together unlikely allies on climate change and with the goal of reaching net-zero carbon emissions in the country by 2050.
  • “Fit for 55” plan of European Union: The European Commission has asked all of its 27 member countries to cut emissions by 55 per cent below 1990 levels by 2030.
  • Last year, China set a target of becoming net-zero by the year 2060.
    • It would also not allow its emissions to peak beyond what they are in 2030.

Why are Net Zero Targets of Less Utility?

  • To tackle the challenge by planting more trees, about 1.6 billion hectares of new forests would be required by 2050.
  • The world needs to cut emissions by 45 per cent by 2030 from 2010 levels to limit global warming below 1.5°C. 
    • The sharpest cuts should be made by “the biggest emitters.”
  • Current Net Zero Targets will only lead to a 1 per cent reduction by 2030.
  • It will add extra pressure on already limited land resources.
    • To tackle only energy sector emissions, a land area nearly the size of the Amazon rainforest is required.
      • It is equivalent to a third of all farmland worldwide.
    • Using only land-based methods may push the food prices up by 80 per cent by 2050.

Way Ahead

  • Nations should shift towards renewable energy sources.
  • Focus on cutting the carbon sources rather than mere mitigation through forest reserves can help.
  • Marine Farming and Blue Economy may help in reducing the pressure on land resources.
