  • CRZs have been classified into 4 zones for the purpose of regulation:
  • CRZ-I: includes ecologically sensitive areas, where no construction is allowed except activities for atomic power plants, defence.
  • CRZ-II: includes designated urban areas that are substantially built up. Construction activities are allowed on the landward side only.
  • CRZ-III: includes relatively undisturbed areas, mainly rural areas. No new construction of buildings allowed in this zone except repairing of the existing ones. However, constructions of dwelling units in the plot area lying between 200-500m of the high tide line is allowed.
  • CRZ-IV: Includes the water area covered between Low Tide Line and 12 nautical miles seaward. Except for fishing and related activities, all actions impugning on the sea and tidal water will be regulated in this zone.
  • CRZ Clearances streamlined: Only such projects/activities, which are located in the CRZ-I (Ecologically Sensitive Areas) and CRZ IV (area covered between Low Tide Line and 12 Nautical Miles seaward) will be required to be cleared by Ministry of Environment, Forest and Climate Change. For, the CRZ-II (urban) or CRZ III (rural) areas, the CRZ clearance will be considered at the state level by the Coastal Zone Management Authority (CZMA).

Why in news?

The 24th Session of the of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP 24) was held in Katowice, Poland.

Key outcomes in Katowice

Rulebook Specifics

  • Accounting Guidance Rules to guide the countries for their Climate pledges (“nationally determined contributions”, NDCs), to compare pledges and to add them up as a global aggregate.
  • Market mechanisms: It provides for the trading of carbon credits i.e. overachievement of NDCs, as well as individual projects generating carbon credits for sale.

Other outcomes:

  • Accounting Rules to prevent “double counting” of emissions reductions by the buyer and seller of offsets could not be finalised.
  • The schemes and methodologies for the implementation of Sustainable
  • Development Mechanism- SDM would be discussed in COP-25. The SDM is intended to replace the Kyoto Protocol’s “Clean Development Mechanism” (CDM) for carbon offsets.
  • Overall Mitigation in Global Emissions (OMGE): It is voluntary and new element under the Paris Agreement, that takes carbon markets beyond the offsetting approaches of the existing markets like the CDM. The primary purpose of OMGE is to deliver on cost-effectively reducing greenhouse gas emissions, rather than creating carbon markets for their own sake.
  • Loss and damage: The Warsaw International Mechanism, which has to deal with averting, minimizing and addressing loss and damage associated with the adverse effects of climate change, has no financial resources to support vulnerable countries.
  • Talanoa Dialogue: The final text simply “invited” countries to “consider” the outcomes of the Talanoa dialogue in preparing their NDCs and in efforts to enhance pre-2020 ambition.
  • Pre-2020: With respect to the “pre-2020” commitments –first agreed by developed countries in 2010 in Cancun – the COP called for developed countries to ratify the Doha Amendment so that it can enter into force. This would extend the Kyoto Protocol on developed country emissions till 2020.
  • The Paris Agreement provides for progress assessments (“stocktakes”) every five years .The first full global stocktake will occur in 2023 in order to prepare for a new round of climate commitments, known as Nationally Determined Contributions (NDCs), by 2025 WBCSD is a global, CEO-led organization of over 200 leading businesses working together to accelerate the transition to a sustainable world.
